  • Techincally Speaking: The P0763 Headache
    Monday, October 1, 2018 12:00 AM
    A call came in to ATSG’s technical help line concerning a 2009 Kia Borrego with a 3.8L engine using a 5-speed RWD transmission called the A5SR2.  This transmission is very similar to the Subaru 5AT transmission, a derivative of Nissan's RE5R05A transmission. Mounted on top of the valve body are the solenoids, a sub-ROM and pressure switch frame assembly (Figure 1). 
  • R & R Tech: Multiple Causes for P0562
    Monday, October 1, 2018 12:00 AM
    A customer brought in a 2010 Dodge Journey AWD with the high-output 3.5-liter V6 engine and the 62TE automatic transmission. With a little more than 83,000 miles on the odometer, the complaint was for no upshifts and stuck in 3rd-gear failsafe mode. This concern had started out as an intermittent issue but now had become more regular.
  • TASC Force Tips: Another Day at the Orifice
    Monday, October 1, 2018 12:00 AM
    Modifying orifice size in valve body separator plates has been practiced as long as automatic transmissions have been in existence. From performance upgrades to attempting to fix problems caused by valve-body wear, opening up orifices can provide positive effects – but can just as easily cause unforeseen problems. To avoid unwanted results, it is necessary to know when to drill, what size to drill to and when not to drill.
  • Tech to Tech: Erratic Shifting
    Monday, October 1, 2018 12:00 AM
    A 2006 Range Rover S equipped with the ZF6HP26 transmission came into the shop with complaints of wrong gear starts and erratic shifting.
    After a wide-open throttle forced downshift and then coming to a stop, the vehicle would take off in third or fourth gear. A scan tool confirmed that the wrong gear starts were commanded by the TCM. The transmission would upshift from third or fourth gear to fifth and sixth gears.
  • Souza Sezz: 10R80/10L90 10-Speed Solenoid Function
    Monday, October 1, 2018 12:00 AM
    In the last article we identified the solenoid locations and shift application. This month I would like to discuss the electronic and hydraulic function of the solenoids and also cover solenoid replacement.
  • Shift Pointers: No Shim and a Short
    Saturday, September 1, 2018 12:00 AM
    Lorenzo Ortiz from Phillips Transmission had a 2005 Acura TSX with the MCTA five-speed transmission come into his shop for repairs. After it was repaired and installed into the vehicle, it had a new problem. The car would not start. The immobilizer lamp was flashing and the scan tool could not communicate with the engine control module, yet all other modules would communicate.
  • R & R Tech: CVTs Are Here; You Can Profit from Them
    Friday, August 31, 2018 12:00 AM
    As CVT transmissions are appearing in our shops with increasing frequency, there still seems to be a degree of hesitance for some shops to take on these jobs. Even if shops do not want to build these units in-house, there are reliable sources for remanufactured units out there that enable them to capture profit on R&R rather than sending a customer down the road to a competitor.
  • Technically Speaking: An ECU Dilemma
    Friday, August 31, 2018 12:00 AM
    A 2009 Toyota Corolla LE with a 1.8L engine and a U341E transmission arrives to a shop with code P2757 Torque Converter Clutch Pressure Control Solenoid Performance (SLU Solenoid) Malfunction stored. The unit was removed and overhauled with a new SLU solenoid and a replacement torque converter. When it was tested, the car seemed to be working well but the Malfunction Indicator Lamp came on after reaching highway speed.
  • Leeward Tech: Extreme Stator Repair
    Friday, August 31, 2018 12:00 AM
    When you are rebuilding a late model converter it is very important to have the correct stator, impeller and turbine. The computers in today’s vehicles are sophisticated enough to pick up small changes in the stall or stall torque ratio in a converter. If a change is detected by the computer it will set a code.
